THE NEW SETPOINT VALUE, AS PER THE ABOVE TABLE, WILL BE ASSOCIATED WITH THE FOLLOWING:
IF THE THERMOSTAT GOES INTO ANTI-FREEZE OR EMERGENCY MODE BECAUSE OF THE AMBIENT PROBE, THE INPUT WILL BE
INHIBITED.
N.B. AIR-SIDE CHANGES TO SEASON ARE PROHIBITED WHILE THE SP INPUT IS CLOSED. THIS IS TO PREVENT ERRONEOUS
STATE CHANGES CAUSED BY SETPOINT VARIATION.
ACCESSORY FUNCTIONS
ELECTRIC HEATER (MANAGED AS A SUPPLEMENTARY DEVICE)
Standard operation of the heater accessory envisages ON-OFF control. In order to control this type of accessory, it is first necessary
to configure the dip-switches accordingly, or rather with dip 5 ON, dip ON and dip 6 OFF (see the dip-switch settings). The electric
resistor intervenes when there is a thermostat operation request and the water temperature is sufficiently low (see the following
graph). In particular, it also shows the enable thresholds in relation to the reduced band/normal band operating mode set (dip 4). It
should be noted that when the thermostat starts up, the heater is OFF, so it will only be activated if the water temperature is below
the enabling threshold (35°C with normal band and 31°C with reduced band).
Activation of the electric heater consequently envisages ventilation management based on the proportional error in the same way as
for the Automatic mode described in the adjustment logic section.
If the fan coil is set to operate with continuous ventilation, when the electric heater reaches the setpoint it will be turned off.
Meanwhile after the post-ventilation phase detailed below, the ventilation will continue at speed V1.
The electric resistor's functionality involves pre-ventilation and post-ventilation phases in relation to its activation and deactivation.
It should be noted that the pre-ventilation phase (20" at V1) always corresponds to the activation of the electric heater, while the
post-ventilation phase always corresponds to the deactivation of the electric heater (60" at V1).
ELECTRIC RESISTOR (MANAGED AS A SINGLE SOURCE OF HEAT)
For fan coil management including cooling through the coil and heating through the resistance, the thermostat must be configured as
shown below:
• Setup for (2/3 way) shut-off valve: dip 1 ON
• Setup for downstream water probe: Dip 2 Off
• Allow 2T+2F management: dip 5 and dip 6 ON
The heater can be activated at any time, regardless of the position of the selector for the thermostat's functioning mode (AUTO-V1-V2-
V3-AUX).
Fan coils that envisage this configuration adopt the air side changeover and only max control.
As for integration management, in this operating mode the heater is also activated in accordance with pre-ventilation and post-
ventilation logic to prevent intervention by protection thermostats.
ELECTRIC HEATER (MANAGED IN INTEGRATIVE/REPLACEMENT MODE)
To manage the fan coil - which allows the electric heater to be used in combined integrative and replacement modes - the thermostat
must be configured as follows:
• Setup for (2/3 way) shut-off valve: dip 1 ON
• Setup for downstream water probe: Dip 2 On
• Allow 2T+2F management: dip 5 and dip 6 ON
Warning: even if the water probe is placed upstream from the valve, the season changeover is based on air temperature.
